Knight of Spears - its an open/public space that appears hostile (given his posture and partially raised spead), so we can assume there are others present. The ground is paved so we can assume he's in a town or city and its daytime and the weather is dry.

Magician - looks to me like a trophy room or a display case in private chambers (only showing his collection to chosen individuals). It's partly shadowed so assuming it's artificially lit or late in the afternoon. There's something about the way he's allowing us to view it that suggests it's an area not everyone is aware of.

2 of Swords - a coastal environment that appears quiet and isolated/separate from the populated area.

Hope that gives you a springboard.
